你好，我和我的团队正试图创建一个应用程序，如果用户点击一个升高的按钮，链接应该得到播放。在过去的20天里，我们正在尝试使用audioplayers插件来做到这一点。我们得到的只是错误和问题。我也添加了整个应用程序文件下面。抱歉链接是在按钮和歌曲的名称是在另一个变量。应用程序链接-驱动链接main.dart

# The following line prevents the package from being accidentally published to

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

# The following line ensures that the Material Icons font is

# the material Icons class.

# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700

# For details regarding fonts from package dependencies,

试试下面的代码，希望对你有所帮助。在pubspec中添加audioplayer依赖项。Yaml文件依赖
创建audioPlay函数:
playSound(){
audioPlayer.play('your audio url here');
}
创建按钮小部件，如:
TextButton(child:'Play',
onPressed:playSound(),
),
